Working on the assumption that you have room in your suitcases and that electronics are 30-40% higher I would bring the following:
Camera: Digital cameras are super cheap in the United States. I have two cameras in Cuenca. I have a Samsung ultra compact that I purchased in Costco for $130 two years ago . I take 80% of my photos with that camera. Why? Good to Very good results and it doesn’t draw attention in the middle of a busy street. The other camera is a Nikon D80 (looks expensive) DSLR. I only use this camera when I am with another person or I am on a trip with a lot of other people. I just think it’s good street smarts not to draw attention to yourself and your vunerable when changing lenses. The Samsung also takes fair to good videos.
Camcorder: Of course this recommendation is for people who want to take videos. I just purchased a Canon HF R20 HD Camcorder that fits in the palm of my hand. Very inexpensive. Great videos recorded on a very inexpensive SD chip and again it does not bring attention from outsiders.
Router: Internet service is our lifeline to our children, grandchildren and friends. I have two Internet services. Total monthly charge $42. One service came with a router and the other didn’t. If you have a good router. Bring it.
Hard Drives. A year ago I would have said bring them down. Now with all the free Cloud services( File storage) around I would say “save the space”. I have a very small 500 gb Seagate Drive. It works great.
T.V’s Blu-Ray DVD Players etc. Again this is a storage conern. I purchased a Samsung 40 inch LED HDTV for about $150 more than in the US. It helps to be fluent in Spanish or have an assertive translator to get the best deal. I purchased a great LG Blu-Ray player for just $15 more than in the U.S.
Miscellaneous: Cables, SD Cards, Surge Protectors etc. Bring them . A 4 ft HDMI cable (connection from your device to a HDTV) cost $18 compared to about $6 in the U.S. The same is true of of memory cards and surge protectors.
I look forward to discussion and questions on other electronic items to bring with you on your trip to Cuenca.
